Description
Technical Field
The invention belongs to the field of composite materials, relates to a preparation method of a composite floor, and particularly relates to a manufacturing method of a painted wood-plastic composite floor.
Background
Wood-plastic composites are one of the fastest growing new polymer composites in the composite field. Extrusion, injection and hot pressing are three main methods for producing wood-plastic composites. The wood-plastic composite board is used in the building industry and the furniture manufacturing industry, and the wood-plastic composite board with excellent performance can replace natural wood to be used for manufacturing wood structure buildings, indoor decoration parts, office tables, cabinet furniture and the like. The floor made of the wood-plastic composite material is accepted by wide consumers due to good durability, good corrosion resistance, moderate price, environmental protection and low carbon. In the manufacturing of wood-plastic composite materials, on one hand, the existing production technology of wood-plastic composite materials requires that the size of wood raw materials is small enough, but the grinding of the raw materials not only increases the energy consumption, but also is a source of dust pollution and noise pollution.
The large-size raw materials are used, the original structure of the raw materials can be kept to be less damaged, so that various performances of the product can be increased, and the effects of energy conservation and noise reduction can be achieved. On the other hand, low-quality wood and fast-growing wood are not effectively utilized, and the low-quality wood needs to be modified to obtain a material with better performance. Though the utilization mode of crushing the fast growing wood and then adding the adhesive to manufacture the artificial board is favorable for improving the utilization rate of the fast growing wood and improving the performance of the board, the problem that people are troubled by environmental pollution and the like can be caused if the adhesive is selected unreasonably. Therefore, how to utilize fast growing wood in a new way is an important issue to be considered, so that the material has more excellent performance and higher value. The patent application publication No. CN103659946A discloses a method for preparing a directional wood-plastic composite board by mixing a wood raw material with a large length-diameter ratio and a plastic sheet, and the method can prevent plastic particles from sliding and leaking to the bottom layer and improve the quality of the wood-plastic composite board to a certain extent.
However, the manufacturing efficiency of the plate material is low, and the problem that the traditional hot pressing method needs long-time pressure maintaining and cooling cannot be solved. Not only is time wasted, but also the temperature of the die needs to be repeatedly raised or lowered in the pressure maintaining and cooling processing process, and energy is wasted. The technology can not fundamentally overcome the defects that the distribution of wood and plastic in the board is not uniform, and the mechanical property and the surface quality of the board are brought by the relative concentration of stress due to the non-uniform inside of the board, so that the high-quality wood-plastic composite floor can not be obtained.
